/**
 * Creates a reducer function for managing the state of query client operations.
 * The reducer updates the state based on actions dispatched related to query transactions.
 *
 * The state is an object where each key represents a unique transaction ID and its value
 * is a `QueryClientRequest` object that contains details about the request, its execution status,
 * any errors that occurred, and the results of the query execution.
 *
 * The reducer handles the following actions:
 * - `request`: Initializes a new query in the state with the given transaction ID.
 *   The state is updated with a new `QueryClientRequest` object which includes the request details,
 *   an empty execution log, an empty error log, and sets the status to 'idle'.
 * - `execute`: Marks a query as active by updating its status to 'active' and logs the execution time.
 * - `execute.success`: Removes a successfully executed query from the state, indicating the query has completed.
 * - `execute.failure`: Updates a query's status to 'failed' and logs the error information.
 * - `error`: Removes a query from the state due to an irrecoverable error, effectively cleaning up its state.
 * - `cancel`: Removes a query from the state if it's canceled, cleaning up any associated state.
 *
 * This reducer is created using a builder pattern provided by `makeReducer` from '@equinor/fusion-observable',
 * allowing for a declarative approach to defining how state is updated in response to actions.
 *
 * @param initial An optional initial state for the reducer. If not provided, defaults to an empty object.
 * @returns A reducer function tailored for managing the state of query client operations.
